Specification of Letters Patent.

Patented April 9, 1907.

Application filed December 8,1906. Serial No. 346,905.

To all whom it may concern:

Be it known that I, PAUL PAULSEN, a sub ject of the King of Prussia, and a resident of Imfelde, near Meldorf, in the Province of Schleswig-Holste n, in the Empire of Germany, have invented a new and useful .[m proved Apparatus for the Treatment of Seed- C orn, of which the following is a specificatlon.

The present invention relates to an improved apparatus for treating the seed-corn with sulfate of copper, the object aimed at by such treatment being the extermination of the fungus sporules. v

Special objects of the invention are to simplify and cheapen the construction and to render more eflicient, serviceable, and durable in operation devices of the kind referred to.

WVith these ends in view the invention consists in the novel combination, arrangement, and adaptation of parts, all as more fully hereinafter explained, shown in the accompanying drawings, and then specifically set out in the appended claim.

In the annexed drawings, Figure 1 illustrates an external view of the device. Fig. 2 represents a central vertical section through the device.

The customary method of treating seedcorn with sulfate of copper with a View of ex terminating the fungus sporules consists in spreading the seedcorn over the threshing floor and in sprinkling the sulfate of copper over same. This method entails considerable disadvantages, prominent among which are the following: The seed-corn is brought in contact with dust and dirt and contaminated thereby. A uniform treatment of the seedcorn is impossible by this sprinkling process. A great expenditure ofsulfate of copper is involved in said. sprinkling process without The method requires an exorbitant amount of time and labor.

My invention obviates the al. ove-cnumerated drawbacks in a simple and ellicient manner. A uniform treatment of the indi vidual grains is insured thereby, while, on the other hand, a considerable saving in time, labor, and in sulfate of copper isefl'ected.

In carrying into practice my nvention I employ, essentially, three superposed receptacles. The lowermost is a tub a,resting on feet I) and provided with uprights c. The middle receptacle 6 is journaled with trunnions d in suitable bearings of the uprights c and adapted to be tilted, for a purpose to be fore-described described in detail later on. tacle is detachably secured in connection with the middle receptacle (2. Both the top and middle roceptaclesf and c are provided with sievebottoms g and 71, respectively. The tub a is fitted with a draw-off cock is shortly above its closed bottom 'i.

I have found it advantageous to construct the three superposed receptacles of wood in a manner similar to casks; but it is obvious that I may adopt, especially inv smaller apparatus, metal or any other suitable material.

The mode of employment of my .hereinbeapparatus is as follows: After taking off the top member f I fill into the middle member 0 the seed-corn to be treated, it being understood that the meshes of the sieve-bottom 71 thereof do not allow the grains to pass therethrough. The top memberf is again connected with the member preferably .in the way illustrated in Fig. 2, and into same is poured the cautcrizing-liquidviz., sulfate of copper. Said liquid penetrates the sieve-bottom g of the top memberfand uni formly sprinkles the seed-corn contained in the middle member 0. After passing through the corn andv doing its destructive work on the way the sulfate of copper issues through the sieve-bottom 7i and collects in the tub (L, from which it may be drawn oil for its renewed employment by opening the stop-cock 7r. During the procedure described. the mid dle receptacle c is secured against tilting movement by the arrangement of hooks m, which lock the member c with the stationary uprights c, as shown in Fig. lVhcn. the treatment of each charge is completed, the hooks are disengaged and the middle member c is tilted around its pivots (Z for the purpose of pouring out the charge contained therein. Handles a facilitate the tilting movement of the receptacle I.

I do not desire. to be understood as limiting myself to the detail wnstruction and arrangement of parts as herein. shown and described, as it is manifest that variations and modilications therein may be resorted to in the adaptation of my invention to varying conditions of use without (.leparting from the spirit and scope of my invention and innxrovomcnts. 1 therefore reserve the right to all such variation and modification as properly falls within the scope of my invention and the terms of the following claim.

hat I do claim as my invention, and desire to secure by Letters .l. atent, is

The top recep- Apparatus for the treatment of seed-corn of the character described, comprising a tub a provided with a draw-off cock is near its closed bottom, two uprights c rising from the top edge of the tub a at points diametrically opposite, a receiver 6 for the seed-corn to be treated having a sieve-bottom h, trunnions d in connection with said receiver adapted to be journaled in bearings of the aforesaid uprights a and enabling the receiver to be tilted, and a strainer f for the liquid poured in de- PAUL PAULSEN.
